Weather Forecast

Wednesday: Mostly cloudy / Light, southeasterly winds/ Freezing sea level.Wednesday night: 20-25 cm new snow / Moderate, southwesterly winds / Freezing level beginning to rise.Thursday: 45-50 mm water / Strong, southwesterly winds / Freezing level 1200m.Friday: Mostly cloudy / Light to moderate, southwesterly winds / Freezing level 800 m.

Avalanche Summary

No new avalanches were reported in this region on Monday.

Snowpack Summary

50-80 cm of recent storm snow is sitting on a knife hard crust. The bond to this crust is slowly gaining strength according to recent reports. The mid and lower snowpack are settled and well bonded with the average snowpack depth at treeline 250-300 cm.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
